SFPD investigate suspicious death in Mission District

Investigators are looking for clues into the death of a man whose body was found on a sidewalk in the Mission District. It happened on Julian Avenue between 15th and 16th in the Mission District. The question is how long was it there before anyone called for help?

Police say the victim was robbed, but he was not stabbed or shot to death. What's odd is they think he was attacked at 2 or 3 a.m., but they say their first call for help came in about five hours later.

A woman called police at 7:45 a.m. Sunday asking them to do a welfare check on a man she saw lying in front of a home on Julian Avenue. When they arrived, Richard Sprague was already dead.
